A pneumatic tire has a plurality of circumferential main grooves extending in a tire circumferential direction and a plurality of ribs partitioned by the circumferential main grooves in a tread portion. When viewing a cross-section from a tire meridian direction a contact patch of the center ribs is formed from a smooth curved line forming a convex on an outer side in a tire radial direction and a contact patch of the shoulder rib is formed from a smooth curved line forming a convex on an inner side in the tire radial direction. The curved line of the center ribs and the curved line of the shoulder rib have a point of intersection. A distance between an extended line of the curved line of the center ribs and the curved line of the shoulder rib increases from the point of intersection towards an outer side in a tire width direction.
